Rush linebacker Adrian Hamilton may have sprained or dislocated his right wrist on special teams. Although X-rays revealed no break, he'll undergo a magnetic resonance imaging exam Friday to determine the extent of the damage.

"He's fine," Harbaugh said of Dumervil. "The really positive thing is nothing really came of this game injury-wise."

Rookie defensive tackle Brandon Williams left the game briefly with trainers after he got his leg chopped out from behind in a pile, but was relieved it was just a scare and went back in to finish the fourth quarter.

"I just got in the pile," said Williams, who finished with four tackles. "The game was moving a little fast in the beginning. I had to calm myself down."

Tandon Doss is battling to remain relevant in the Ravens' wide receiver conversation.

Doss set aside the frustration of a reception nullified by offsetting penalties and a lost fumble that was ultimately ruled a dropped pass.

During the Ravens' 27-23 win over the Atlanta Falcons on Thursday night at M&T Bank Stadium, Doss' first reception of the preseason translated into a 5-yard touchdown catch late in the fourth quarter on a pass from backup quarterback Tyrod Taylor.

Doss is competing for the second or third receiver position, but was shut out in the Ravens' preseason opener as he had a dropped pass on an accurate Joe Flaccothrow.

"It felt great," Doss said. "I'm used to catching passes from Joe and Tyrod. I felt my timing was good from Joe and from Tyrod, and it felt good to make a big play. I feel comfortable with Joe, but he hasn't been able to hit me yet, and he hasn't looked my way yet. Once we get that going, we should be good."

Jackson scores

Reserve cornerback Asa Jackson is suspended for the first eight games of the season for violating the NFL performance-enhancing drug policy,increasing the importance of these preseason games.

Jackson made the most of an opportunity in the second half with a 78-yard punt return for a touchdown where he raced up the sideline.

"The return was set up on the wide side of the field and all the blocks matched up great," Jackson said. "I didn't even sell it too well to the left before I cut back right. Everyone had great leverage. They just made that wall and the blockers made that easy for me. I just had to get to the sideline. It set up perfect."

Jackson said he's aware of the impression he needs to leave on the coaching staff to hold onto his roster spot when his punishment is over.

"It's true," Jackson said. "I'm just trying to make them miss me while I'm gone. All I can do is play as hard as I can and continueto try and improve on the things I'm not doing so well. I need to eliminate themistakes."

Nickel look

The Ravens opened the game with rookie inside linebacker Arthur Brown with the first-team defense along with cornerback Chykie Brown on the field.

That's because the Ravens were in their nickel defense to match up with the Falcons' pass-oriented offense.

A second-round draft pick, Arthur Brown was substituted for on the following down by Josh Bynes. Bynes started the opening game of the preseason against the Tampa Bay Buccaneers and is listed first on the depth chart.

Bouncing back

David Reed has been hampered by a recurring groin injury and sat out the first game. Against the Falcons, he returned three kickoffs for 94 yards in the first half.
